二、進(jìn)口氣動薄膜調(diào)節(jié)閥主要特點：

1.頂?shù)?、層雙導(dǎo)向雙座調(diào)節(jié)閥，工作時穩(wěn)定性好。

2.有兩個閥芯和閥座，采用“四通”閥體，可以方便地由正裝改裝成反裝，氣關(guān)閥變氣開閥。

3.閥體按流體動力學(xué)原理設(shè)計的等截面低流阻流道，額定流量系數(shù)大。

4.不平衡力小，允許使用壓差較大。

5.執(zhí)行機(jī)構(gòu)采用多彈簧結(jié)構(gòu)，高度減小30%。重量減輕30%。

6.可調(diào)范圍大，固有可調(diào)比為50%。

7.LXNV型波紋管密封型調(diào)節(jié)閥對移動的閥桿形成了完全密封，堵絕流體外漏。

8.LXNJ型調(diào)節(jié)閥帶有保溫夾套，用于流體冷卻后易結(jié)晶、凝固造成堵塞的場合。

2、 Main features of imported pneumatic diaphragm control valve:
1. Double guide and double seat control valve at the top and bottom, with good stability.
2. There are two valve cores and valve seats, and the "four-way" valve body is adopted, which can be easily refitted from normal installation to reverse installation, and the gas closing valve can be changed into gas opening valve.
3. The valve body is designed according to the principle of fluid dynamics, with low flow resistance and constant cross-section, and large rated flow coefficient.
4. The unbalanced force is small and the allowable pressure difference is large.
5. The actuator adopts multi spring structure, which reduces the height by 30%. 30% weight reduction.
6. Wide adjustable range, inherent adjustable ratio is 50%.
7. Lxnv bellows seal type control valve forms a complete seal to the moving valve stem to block fluid leakage.
8. Lxnj type control valve is equipped with heat preservation jacket, which is used in the occasions where the fluid is easy to crystallize and solidify after cooling.

三、進(jìn)口氣動薄膜調(diào)節(jié)閥描述：

德國DE LOCKE洛克進(jìn)口氣動薄膜調(diào)節(jié)閥由氣動薄膜執(zhí)行機(jī)構(gòu)和調(diào)節(jié)閥兩大部分組成，它與氣動調(diào)節(jié)器，減壓閥、定位器或其他儀表配合使用，達(dá)到控制管道內(nèi)的溫度、壓力、液位、流量等工藝參數(shù)。單座調(diào)節(jié)閥具有易密封，泄漏量小的優(yōu)點，但平衡力較大，故工作壓差不宜過高。雙座調(diào)節(jié)閥具有流量系數(shù)大，不平衡力較小的特點，因而使用廣泛。主要用于調(diào)節(jié)氣體、液體、蒸汽等介質(zhì)，用在電廠，鋼鐵廠，制糖，洗煤選礦等化工領(lǐng)域。

3、 Description of inlet pneumatic diaphragm control valve:
The pneumatic diaphragm control valve imported from Germany de lock is composed of pneumatic diaphragm actuator and control valve. It is used together with pneumatic regulator, pressure reducing valve, positioner or other instruments to control the temperature, pressure, liquid level, flow and other process parameters in the pipeline. Single seat control valve has the advantages of easy sealing and small leakage, but the balance force is large, so the working pressure difference should not be too high. Double seat control valve has the characteristics of large flow coefficient and small unbalanced force, so it is widely used. It is mainly used to regulate gas, liquid, steam and other media. It is used in power plant, iron and steel plant, sugar making, coal washing, mineral processing and other chemical fields.
